vfs_permission(MAY_EXEC) checks if the filesystem is mounted with "noexec", so there's no need to repeat this check in sys_uselib() and open_exec().

permission() checks that MAY_EXEC is only allowed on regular files if at least one execute bit is set in the file mode. generic_permission() already ensures this, so the extra check in permission() is superfluous. If the filesystem defines it's own ->permission() the check may still be needed. In this case move it after ->permission(). This is needed because filesystems such as FUSE may need to refresh the inode attributes before checking permissions. This check should be moved inside ->permission(), but that's another story.

Hello, I fixed and tested a small bug in lib/sort.c file, heap sort function. The fix avoids unnecessary swap of contents when i is 0 (saves few loads and stores), which happens every time sort function is called. I felt the fix is worth bringing it to your attention given the importance and frequent use of the sort function.

There have been issues with non-latin1 diacritics and unicode. http://bugzilla.kernel.org/show_bug.cgi?id=7746 Git 759448f4 `Kernel utf-8 handling' partly resolved it by adding conversion between diacritics and unicode. The patch below goes further by just turning diacritics into unicode, hence providing better future support. The kbd support can be fetched from http://bugzilla.kernel.org/attachment.cgi?id=12313 This was tested in all of latin1, latin9, latin2 and unicode with french and czech dead keys. Turn the kernel accent_table into unicode, and extend ioctls KDGKBDIACR and KDSKBDIACR into their equivalents KDGKBDIACRUC and KDSKBDIACR. New function int conv_uni_to_8bit(u32 uni) for converting unicode into 8bit _input_. No, we don't want to store the translation, as it is potentially sparse and large.

This adds the MMF_DUMP_ELF_HEADERS option to /proc/pid/coredump_filter. This dumps the first page (only) of a private file mapping if it appears to be a mapping of an ELF file. Including these pages in the core dump may give sufficient identifying information to associate the original DSO and executable file images and their debugging information with a core file in a generic way just from its contents (e.g. when those binaries were built with ld --build-id). I expect this to become the default behavior eventually. Existing versions of gdb can be confused by the core dumps it creates, so it won't enabled by default for some time to come. Soon many people will have systems with a gdb that handle these dumps, so they can arrange to set the bit at boot and have it inherited system-wide. This also cleans up the checking of the MMF_DUMP_* flag bits, which did not need to be using atomic macros.

Two threads, T1 and T2. T2 ptraces P, and P is not a child of ptracer's thread group. P exits and goes to TASK_ZOMBIE. T1 does wait_task_zombie(P): P->exit_state = TASK_DEAD; ... read_unlock(&tasklist_lock); T2 does exit(), takes tasklist, forget_original_parent() does __ptrace_unlink(P) but doesn't call do_notify_parent(P) because p->exit_state == EXIT_DEAD. Now, P is not visible to our process: __ptrace_unlink() removed it from ->children. We should send notification to P->parent and release P if and only if SIGCHLD is ignored. And we have 3 bugs: 1. P->parent does do_wait() and gets -ECHILD (P is on ->parent->children, but its state is TASK_DEAD). 2. // wait_task_zombie() continues if (put_user(...)) { // TODO: is this safe? p->exit_state = EXIT_ZOMBIE; return; } we return without notification/release, task_struct leaked. Solution: ignore -EFAULT and proceed. It is an application's bug if we can't fill infop/stat_addr (in case of VM_FAULT_OOM we have much more problems). 3. // wait_task_zombie() continues if (p->real_parent != p->parent) { // Not taken, it was untraced'ed ... } release_task(p); we released the task which we shouldn't. Solution: check ->real_parent != ->parent before, under tasklist_lock, but use ptrace_unlink() instead of __ptrace_unlink() to check ->ptrace. This patch hopefully solves 2 and 3, the 1st bug will be fixed later, we need some cleanups in forget_original_parent/reparent_thread. However, the first race is very unlikely and not critical, so I hope it makes sense to fix 1 and 2 for now. 4. Small cleanup: don't "restore" EXIT_ZOMBIE unless we know we are not going to realease the child.

This adds the linux/elfcore-compat.h header file, which is the CONFIG_COMPAT analog of the linux/elfcore.h header. Each arch that needs to fake out fs/binfmt_elf.c for its compat code can use this header to replace the hand-copied definitions of the compat variants of struct elf_prstatus et al. Only the pr_reg field varies by arch, so asm/{compat,elf}.h must define compat_elf_gregset_t before linux/elfcore-compat.h can be used. It's a clean-up that every arch with compat core dumping code can benefit from. I only touched the ones I have handy to test at home. Doing the same for each other arch should be straightforward, and I'm happy to offer tips.

The current code skips the check to verify whether the filesystem was previously cleanly unmounted, if (flags & UFS_ST_MASK) == UFS_ST_44BSD or UFS_ST_OLD. This looks like an inadvertent bug that slipped in due to parantheses in the compound conditional to me, especially given that ufs_get_fs_state() handles the UFS_ST_44BSD case perfectly well. So, let's fix the compound condition appropriately.

With or without this patch, multi-threaded init's are not fully supported, but do_exit() is completely wrong. This becomes a real problem when we support pid namespaces. 1. do_exit() panics when the main thread of /sbin/init exits. It should not until the whole thread group exits. Move the code below, under the "if (group_dead)" check. Note: this means that forget_original_parent() can use an already dead child_reaper()'s task_struct. This is OK for /sbin/init because - do_wait() from alive sub-thread still can reap a zombie, we iterate over all sub-thread's ->children lists - do_notify_parent() will wakeup some alive sub-thread because it sends the group-wide signal However, we should remove choose_new_parent()->BUG_ON(reaper->exit_state) for this. 2. We are playing games with ->nsproxy->pid_ns. This code is bogus today, and it has to be changed anyway when we really support pid namespaces, just remove it.

The Linux ELF loader is quite complicated and messy code (that could probably need a rewrite, but that's a different chapter). One particular messy part in it is the support for non ELF a.out ld.sos. This was originally added to make transition from a.out to ELF easier because an a.out ELF ld.so could be still build using an older a.out toolkit. But by now that should be fully obsolete and removing it would clean up binfmt_elf.c up a bit. I propose to deprecate this support and remove for 2.6.25. Drawback is that someone still runs their system with a.out ld.so they would need to update the ld.so when updating to a new kernel. This patch just adds an entry to the deprecation file and a printk warning users.
